Are mammals the most capable of learning?

Mammals are generally considered among the most capable of learning due to their complex brains and social structures. Species like dolphins, primates, and elephants exhibit advanced problem-solving skills, social learning, and communication abilities. However, other animal groups, such as birds and cephalopods, also demonstrate significant learning capabilities. Thus, while mammals are highly adept learners, they are not the sole leaders in this area among all animal taxa.
